    Timers freeze after about 1 sec.

      Hi, I am using the timer startup as used in most of the sample apps by inserting the following two lines in the _create() function:

       

          bleprofile_regTimerCb(temperature_sensor_fine_timeouty, temperature_sensor_timeout);

          bleprofile_StartTimer();

       

      The fine timer is set to 100ms in the BLE_PROFILE_CFG:

              /*.fine_timer_interval            =*/ 100,  // ms

       

      I use the fine timer for running all the repetitive tasks that need to occur at a regular interval. The normal timer (which I think is always set to 1 sec), using the temperature_sensor_timeout callback, is an empty function.

       

      The problem that I am facing is that the custom 20736 board runs normally for about 1 sec, and then it freezes. A copy of the debug trace is included below. One thing that I noticed in the trace is that normal timer shows a setting of 0 sec:

              15:46:21   Normal Timer(0 s, 0 tick)

       

      Is this how it is supposed to show up? What is the reason for timers to lock up? I have spent plenty of hours looking through the discussions and trying various alternatives, but nothing seems to work, and so I am stuck with this issue.

       

      I also upgraded SDK from 2.1.1 to 2.2.1, but that did not change the outcome.

       

      Please help!!

      hanks.
